10.2 Switching outputs
Each switching output consists of a relay, the switching contacts of which can be connected
as N/C or N/O. For each switching output, the following parameters can be set during normal
operation (see chapter 7.2 Summary of the Basic Settings Menu):
•
Assignment to sensor
•
Switching function (switch point and hysteresis or switching window mode)
•
Switching direction (relay activated or relay deactivated)
•
Switch-on delay
•
Switch-off delay
10.2.1 Switching mode
During normal operation, switch point and hysteresis or switching window can be set as the
switching mode of a switching output.
10.2.1.a) Switch point and hysteresis (SP)
In the switch point and hysteresis mode, a switching function is activated if (while rising in
value) the measured value of a sensor reaches the value of the switch point. A switching
function is deactivated if (when falling in value) the measured value of a sensor falls below
the value of the switch point by the value of the hysteresis. This defines the switch-back point
as the difference between switch point and hysteresis.
The switch point and hysteresis can be set individually for each switching output. The follow-
ing setting ranges apply:
•
Switch point
•
Hysteresis
10.2.1.b) Switching Window (Win)
In switching window a defined range is monitored. A switching function is activated if the
measured value of a sensor is outside the window and reaches one of the switch points. A
switching function is deactivated if the measured value of a sensor is within a switching
window and reaches one of the switch-back points. The switch-back points depend on the
switch points (upper switch-back point = upper switch point plus 1 % and lower switch-back
point = lower switch point minus 1 %). This difference between switch point and switch-back
point prevents unwanted switching from occurring.
